Business intelligence (BI) refers to techniques used to analyze and report on business data for purposes like predictive analytics and decision making. BI uses technology to analyze mostly internal structured data from sources like marketing, email, and finance applications. Competitive intelligence analyzes external structured and unstructured data from sources like news, jobs, and people. BI and CI together form a decision support system that analyzes both internal and external data to generate reports, forecasts, and predictions to help with decision making. Some challenges with BI include ensuring data quality and access, and selecting the right tools. Sample BI reports could analyze preferred vendors, consultant performance, marketing effectiveness, and potential new clients.
